'A

In the operat1on of the ,embodiment thel compartments of the hopper 10 are filled Wlth differently colored material which is discharged in a continuous stream upon the base sheet 12. The reciprocating p ate is suspended from the hopper between it and the base sheet and is inclined in such a manner that the falling material will flow over its ribbed face. The reciprocation of the mixing plate not only intermingles and blends the vari-colored particles into nonuniform mixtures which produce a variegated surface without defined or readily distinguishable areas of colors, but avoids any appreciable regularity either in blending size or arrangement of the differently colored patches.`

While I have illustrated and described in detail the preferred embodiment of my invention, it should be clearly understood that the disclosure is merely for purposes of illustration and that many modifications and variations Will naturally occur to those skilled inthe art. Moreover it is not indispensable to.employ all features of the invention conjointly since various features may be employed in other sub-combinations and combinations.
